Abstract
Methods and systems are provided for continuously producing cast metal components. An exemplary method includes feeding molten metal into a first mold at a fill station; maintaining a pressurized chamber at an elevated pressure; moving the first mold into the pressurized chamber, wherein the molten metal solidifies in the first mold under the elevated pressure; and removing the first mold from the pressurized chamber.
Claims20
A method for continuously producing cast metal components, comprising:
- feeding molten metal into a first mold at a fill station;
- maintaining a pressurized chamber at an elevated pressure;
- moving the first mold into the pressurized chamber, wherein the molten metal solidifies in the first mold under the elevated pressure;
- and
- removing the first mold from the pressurized chamber.
An in-line casting system comprising:
- a mold assembly station for assembling a mold;
- a fill station for filling the mold with molten metal;
- a pressurization station for densifying the molten and/or semi-solid metal under an elevated pressure;
- and
- a casting/mold disassembly station for disassembling the mold and a casting formed therein.
